c3. The upper half capsule body c1 and the lower half capsule body c2 are slidable with each other, and the upper end of the upper half capsule body c1 and the lower end of the lower half capsule body c2 are each formed in a hemispherical shape. I have.

The capsule member C is an outer cylinder s1 of the storage member S.
And the lower half capsule body c2 of the capsule member C
Is inserted into the trumpet-shaped hole s8 of the support member s7 fitted in the outer cylinder s1, and is placed on the support member s7. After the capsule member C is stored in the outer cylinder s1 of the storage member S, the movable support member s9 is inserted into the slit s6 formed in the outer cylinder s1 and the flange s2, and the support cylinder of the movable support member s9 is inserted. thread insertion hole s formed in s11
The upper part of the capsule member C is inserted into fifteen trumpet-shaped holes s12 and columnar holes s13. Thus, the capsule member C stored in the outer cylinder s1 of the storage member S is
1 is configured to be supported by the support member s7 and the movable support member s9 inserted into the slit s6.

As described above, the capsule member C housed in the outer tube s1 of the housing member S includes the support member s7 fitted in the outer tube s1 and the moving support member s9 inserted in the slit s6. Between the outer peripheral surface of the capsule member C and the inner peripheral surface of the movable support member s9, and between the outer peripheral surface of the capsule member C and the inner peripheral surface of the outer cylinder s1. A gap 10 is formed. The capsule member C housed in the outer tube s1 of the housing member S is formed by the upper half capsule body by the support member s7 fitted in the outer tube s1 and the movable support member s9 inserted in the slit s6. c1 and a coil spring c3 arranged in the lower half capsule body c2 are configured to be compressed. Therefore, the lower part of the lower half capsule body c2 of the capsule member C contacts the slope s7 ′ forming the trumpet-shaped hole s8 of the support member s7 fitted in the outer cylinder s1, and the upper half capsule body c1
Is in contact with a slope s12 ′ forming a trumpet-shaped hole s12 formed in the support cylinder s11 of the movable support member s9.

The yarn y is introduced from the trumpet-shaped guide hole s3 of the yarn guide member s4, and then the hole s8 of the support member s7 is opened by the self-weight of the coil spring c3 disposed inside the capsule member C and the capsule member C. The lower part of the lower half capsule body c2 of the capsule member C abutting on the slope s7 'to be formed, and the slope s8 forming the hole s8 of the support member s7.

An upper portion of the upper half capsule body c1 of the capsule member C in contact with the movable support member s
The slope s12 of the hole s12 formed in the support cylinder s11 of No. 9
12 ′, and is drawn out above the movable support member 9.

The yarn y pulled out from the yarn supplying bobbin 1 is supplied to a friction disk type false twisting device 4 located above the fluff control member 3 via the balloon control cylinder 2 and the fluff control member 3. Thereafter, the paper is wound around a winding package 8 while being traversed by a traverse drum 7 through an automatic piecing device 5 and a yarn clearer 6.

A false twist is applied to the traveling yarn y by a friction disk type false twisting device 4 provided on the yarn path between the yarn supplying bobbin 1 and the winding package 8, and the friction disk type false twisting device 4 is provided. In the lower twisting region, the yarn y is twisted in a predetermined direction, and the twist is controlled by the fluff control member 3 provided below the friction disk type false twisting device 4 by the fluff control member 3. The propagation of the twist in the downward direction is controlled (in this sense, the fluff control member 3 also functions as a twist stopping member), so that the yarn y
Is subjected to effective twisting. As described above, the false twist is given to the yarn y, and the fluff projecting from the surface of the yarn y is twisted, and the fluff binding is performed.

Next, a description will be given of a means for threading the fluff control member 3 which is performed after the yarn y wound around the yarn supplying bobbin 1 is exhausted and the yarn supplying bobbin 1 is newly disposed.

After the yarn y wound on the yarn supplying bobbin 1 is exhausted, the balloon control cylinder 2 is raised, and the fluff control member 3 is placed in the balloon control cylinder 2 as shown in FIG. And the balloon control cylinder 2 is brought into contact with the stopper s10 of the moving support member s9, thereby lifting the moving support member s9 constituting the fluff control member 3. After lifting the movable support member s9 to such an extent that the movable support member s9 does not completely come out of the slit s6, the lifting of the balloon control tube 2 is stopped. As described above, by lifting the movable support member s9, the gap between the slope s12 ′ of the trumpet-shaped hole s12 formed in the support cylinder s11 of the movable support member s9 and the upper half capsule body c1 of the capsule member C is obtained. Then, a gap through which the yarn y passes is formed.

Next, the air jet nozzle 9 disposed below the yarn supplying bobbin 1 is actuated to move the winding end yarn end inserted into the inner hole of the yarn supplying bobbin 1 from the top hole of the yarn supplying bobbin 1. While blowing up, by supplying compressed air from a compressed air supply source (not shown) to the air injection holes s19 formed in the storage member S, the air ejected from the outlet s18 'toward the capsule member C is supplied. In the fluff control member 3, an upward airflow is formed. Therefore, the yarn y blown up from the top hole of the yarn supplying bobbin 1 is
The gap formed between the lower part of the lower half capsule body c2 of the capsule member C lifted by the compressed air and floating and the slope s7 ′ of the support member s7 fitted in the outer cylinder s1, Annular gap 10 and moving support member s9
Trumpet-shaped hole s12 formed in the support cylinder s11
Is pulled out from the upper part of the fluff control member 3 through the gap formed between the slant surface s12 ′ of the capsule member C and the upper half capsule body c1 of the capsule member C, and the threading to the fluff control member 3 is completed.

The yarn y pulled out from the fluff control member 3 is
After being sucked and held by a relay suction pipe (not shown) arranged above the fluff control member 3, it is introduced into the automatic piecing device 5. At this time, the annular gap 1 of the fluff control member 3
The fly waste accumulated at 0 or the like is sucked into the relay suction pipe along with the yarn y passing through the annular gap 10 by air flow,
It is collected in a dust box (not shown).

At the time of threading through the fluff control member 3, by supplying compressed air from a compressed air supply source (not shown) to an air injection hole s19 formed in the storage member S, the fluff control member is Although the threading to the fluff 3 is performed, weak compressed air is always supplied to the air injection holes s19 to generate an upward airflow in the annular gap 10 of the fluff control member 3 so that fluff is generated. You may comprise so that the fly waste accumulated in the control member 3 may be removed.

[0025]

Since the present invention is configured as described above, the following effects can be obtained.

Since the capsule member is supported by the moving supporting member, the moving of the moving supporting member at the time of threading the fluff control member facilitates the movement of the capsule member. Threading can be performed quickly and reliably.

Since the movable support member is moved by the balloon control cylinder, the movable support member can be moved when threading the fluff control member without providing a special device.

At the time of threading through the fluff control member, an upward air flow is generated in the fluff control member, so that the capsule member is floated, and a gap through which a thread can be inserted into the fluff control member is formed. So that
It becomes possible to automate the threading to the fluff control member. Moreover, using this air flow, the fly cotton accumulated in the fluff control member can be cleaned every time the yarn feeding bobbin is replaced,
It is possible to reliably prevent malfunction of the device due to the accumulation of fly wool.
